Biotransformation and detoxification of inorganic arsenic in a marine juvenile fish Terapon jarbua after waterborne and dietborne exposure

► Compare the biotransformation of As(III) and As(V) following waterborne and dietary exposures. ► No significant effect on fish growth performance after waterborne and dietary As exposure. ► Both As(III) and As(V) were rapidly biotransformed to the non-toxic arsenobetaine. ► Binding with metallothionein-like proteins was another detoxification strategy for fish. ► This study elucidated that As(III) and As(V) had little potential toxicity on marine fish.
